Using prefixes with config files

[ceng-p]

Hello!

In the "Working with environment variables" section there is this example.

SetEnvPrefix("spf") // will be uppercased automatically
BindEnv("id")

os.Setenv("SPF_ID", "13") // typically done outside of the app

id := Get("id") // 13

If I want to work with a config file, let's say dev.env that contains variables that have the same prefix "spf". Is there a way to get those config variables without specifying "SPF" in the call to Get ?

For example with this file

spf_user_id=abc

I would have to call userId := Get("spf_user_id") instead of just calling Get(user_id)

Not at the moment. You could try using RegisterAlias, but I'm not sure if it's going to work in this case.

A workaround I'd try is loading env vars from the file using some dotenv tooling.
